The soft layer of ECC media usually possesseshigh saturation magnetization and also high demagnetizing energy density.

ECC介質(zhì)由交換耦合的軟磁層與硬磁層構(gòu)成国产男女激情一区二区，它是通過軟磁層與硬磁層的磁矩在磁化反轉(zhuǎn)過程中的非一致轉(zhuǎn)動來達到降低矯頑力的效果av呦呦，而無外場時熱反轉(zhuǎn)仍為一致轉(zhuǎn)動，因而能保持較高的熱穩(wěn)定性91午夜黄色视频。

These results suggest that when the demagnetizing energy of soft layer is unavoidablethe application of high Ms soft layer can help to decrease the switching field,maintainthe thermal stability,improve the uniformity,reduce the thickness of interlayer andtotal recording layer,and will not worsen the signal to noise ratio.

The CoFe2O4/TiO2 magnetic nano-photocatalysts has fairly good magnetic property. The X-ray diffraction, transmission electron microscopy and ultraviolet-visible technique were used to analyze the phase structure, size and spectrum response scope of the samples. The XRD indicated the anatase TiO2 was formed when TCF modified by plasma. The size of CoFe2O4 particles was about 20 nm. The diameter of CoFe2O4/TiO2 particles is in the range of 30~40 nm. So the shell of TiO2 enwraps closely around the core and the thickness is in the range of 10~20 nm.
